[I] [Bug] spark-doris-connector，Unknown column 'null' in 'table list' [doris]
para-99 opened a new issue, #57882:
URL: https://github.com/apache/doris/issues/57882
### Search before asking
- [x] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues.
### Version
doris 2.1, My Spark version is 3.4.3, and the Spark-Doris-Connector version is 25.1.0.
### What's Wrong?
I am using the Spark-Doris-Connector to read data from Doris, then perform some computations, and finally write the results back to Doris.
When I use the following Java code to read from Doris:
String filterString = "cust_no = '111'";
sparkSession.read()
.format("doris")
.option("doris.table.identifier", "busidb.tb_tx")
.option("doris.fenodes", "123")
.option("user", "123")
.option("password", "123")
.option("doris.filter", filterString)
.load();
Then I perform some computations, and finally write the result (allRslt) back to Doris using:
allRslt.write()
.format("doris")
.option("doris.table.identifier", "busidb.tb_rslt")
.option("doris.fenodes", "123")
.option("user", "123")
.option("password", "123")
.mode(SaveMode.Append)
.save();
I get the following error:
query plan failed, exception: errCode = 2, detailMessage = Unknown column 'null' in 'table list'
However, I have printed the columns of allRslt, and there is no column named "null" in it.
More strangely, if I read the data using .read().jdbc().load()(e.g., from a traditional database like MySQL) instead of Doris, this issue does not occur.
Has anyone else encountered this problem? Is this a problem with the Spark-Doris-Connector?

This looks like a Spark-Doris-Connector issue where pushed-down filter or projection metadata becomes inconsistent during write, resulting in an invalid column reference (null) in the generated Doris query plan
error is query plan failed
Unknown column 'null' in 'table list'
and .option("doris.filter", "cust_no = '111'")
This appears to be a Spark-Doris-Connector issue rather than a Spark SQL problem. The error originates from Doris query planning, and only occurs when the source is Doris and doris.filter is used. When reading via JDBC, the same write succeeds, which suggests the dataset schema itself is valid. My guess is that filter or projection metadata from the Doris scan is leaking into the write path, resulting in an unresolved column being serialized as null in the generated Doris query.
